AT&T is on Line 2 for your Apple corp.......... UH-OH

How many minutes on your phone plan do you use while in a wireless hotspot? I read an article today about a new iPhone app that allows you to make calls over the internet using your iPhone. This does not use minutes from AT&T. This app allows you to have a whole other phone line as well. The developer of this app has some balls to take on a corporate giant, and my hope is that many people take advantage of this while it lasts.

I feel like AT&T is not going to let this stand. What phone company would sit by idle while people are making calls, not using their minutes? If someone has this app and works around a wi fi hotspot, they can save a ton of minutes. THis app does cost 15 dollars a month, but that could wind up saving some people a ton of money in the long run.
